To all whom it may concern Be it known that I, EDWARD A.. HALBLEIB, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented'certain new 'and useful Improvements in Powerrliransrnission Mechanism, of which the following is a specification. l

This invention relates to mechanism for supporting and actuating an electric generator in connection with an internalcombustion engine.

rlhe object ofthe invention is to produce an arrangement by which a generator may be connected with driven thereby, or used as a source of power to start the engine, without any substantial change in the construction or'arrangement engine or of its accessories, and particularly withthegenerator located alongside the engine in the space usually available within the bonnet by which the engine is inclosed. To this end li employ anv arrangement'in which the Ygenerator is carried on. a support mounted alongsidey the engine, and I connect the generator-shaft with' the engine-shaft by means including a chain and sprocket wheels, and provide for the necessary adjustment of the tension of the chain by the novel means for that purpose hereinafter described.

Other objects and features of -the`inven tion will be set forth in connection with the following description of the preferred embodiment of the invention.

In the accompanying drawings:-Figure 1 is-a front-elevation of power-transmission mechanism embodying the present invention; and Fig. 2 is a plan-view of the same,

with the additionof a fan shaft. f

The invention is shown as applied to the engine of a well-known type'of automobile, the cylinders 5, the crank-case 6, the crankshaft 7, and the gear-housing 8 of the engine being all of ordinary form. The drawings illustrate also a generator 9 of ordinary form, which is preferably adapted to operate-also as a motor to start the engine, and is provided with the usual armature-shaft 10. In the'illustrated mechanism employ a upon the countercountershaft 11, through which the arma-- ture-shaft is connected with the crank-shaft ofthe en ine. This countereshaft is located above an parallel with the crank-shaft 7,

an automobileengine and.

and is provided with a sprocket-wheel 12 `Irom which a sprocket-chain 13 extends to -a sprocket-wheel 14 fixed on the crank-shaft.

second sprocket-wheel 15 on the countershaft is connected, by a chain 16, with a sprocket-wheel 17 on the armature-shaft 10. These chains and sprocket-wheels aiord a positive connectionY between the armatureshaft and the crank-shaft at all times, and the ratio of the diameters `of `the several sprocket-wheels is such as to make a speedreduction between the generator and the crank-shaft, so that the generator may be driven at high speed when the engine is running, and may also apply its power eectively to start the engine.

The counter-shaft 1 1 is'supported in bearings in a yoke 18, which is provided with an arm 19 pivoted upon a stud 20 projecting from the engine. This stud is one of the studs or screws normally employed to hold the cover of the gear-housing 8. The bearing-yoke 18 is thus supported by the stud 20, and as a further -provision for the same end it has a depending arm 21, which carries an adjusting-screw 22 at its lower end, the lower end of the screw, in turn, bearing upon the head 23 of a screw conveniently located on the crank-case of the engine. AThe screw 22 sup orts the arm 21 and the bearing-yoke against the pull of the chain 13, but the tension of the chain may he adjusted, lto take up slack, by turning the screw 22, which is then fixed in adjusted position by a lock-nut 2e. To further support the bearing-yoke the arm 21 is provided with a slot 25 which receives a stud 26 screwed into th'e front of the crank-case of the engine. The slot 25 permits the arm, 21. to swing about .the stud 20 for the purpose of adjusting the chain 13, as just defscribed, but thestud 26 steadies the arm against movement in a fore-and-aft direction.

The generator is carried by a support 27 having a concave seat, which fits the generator-casing, and depending arms which are mounted, at their lower ends, upon pivots 2 8 fixed in a base-member 29 screwed to the crank-case of the engine. The casing of the generator is generally-cylindrical in form, -so that it may be turned in its seat on the support 27, but it isnormally fixed thereon by means of a device comprising straps 30, fixed to the support, and connected at their upper ends by a T-bolt 31. Toprovideor theadjustment of the chain.v 16 ithe genen. nel is provided with :aintegral.

the chain 16. rlhe ladjListing-mechanism i'sdesigned to proportion the two simultaneous adjustments to the wear to which the chains are respectively subjected, and to permit this wear to be equalize'd'the chains are made both of the same length andinterchangeable, so that they maybe interchanged occasionally. ln setting up the apparatus in the first place, however, independent adjustment of the chains maybe desirable, and

this is provided for -in the arrangement described, iior, on loosening the T-bolt 31 the generator lmay be' turnedfinl its seat, thus swingingthe -slotted arm 32 .with respect to 50 the stud 34, and adjusting the chain 16 without any' corresponding adjustment of the chain 13.

The counter-shaft 11 is arranged to occup-y :the positionoccupied normally by a 35 belt-driven fan-shaIt, and accordingly the Vcounter-sliaft may be utilized, in place of the usual fan-'shaft,.as a means'for actuating thegfan. In Fig. 2 a fan 36 is shown as zmounted upon the forward end of the im counter-shaftThe sprocket-wheel 14 and the, chain 13 also occupy the positions usually occupied by a pulley and a belt, -respectively, for driving the fan, while the generator and its lsupport occupy positions within the bonnet of the automobile'which are normally vacant. For these reasons, and for the further reason that, the various studs andscrews employed to supportthe mechanism are -merely substituted lfor those already .found in similar positions,it will be apparent that the vpresentY mechanism is adapted for convenient application to an automobile of' ordinary construction, with` out any substantial change inthe construction or arrangement of its parts, while the generator .isjalso located in a; position Where it is'conyeniently accessible for inspection or repair;A Q A In an arrangem nt such asthat described the. chains lare sometimes subjected to heavy tension, when fthe direction of rotation of the, armature-shaft is suddenly'reversed in consequence of aback-kick in the-engine.

$5 In the. present arrangement,however, notwithstanding the fact that all of the parts are relatively movable for the purpose of adjusting them' .to fit various engines Vand to take'up slack in Visvl rigidly resisted, for the bearing-yoke, with 'its three integral arms, constitutes, in etlect, a.rigid triangle having three points of support, at the ends of its three-arms,

which prevent'movements either in, ortrans- 'verse to, its plane.

My invention is not limitedto the embodiment thereof hereinbefore described vand ,illustrated in vthe accompanying drawings,

for' adjusting the tension of saidphaint'and means for: normally preventing such rotation of the generator inits support.
